Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers

Hello, first of all I'd like to apologise because I am new to this forum, but I need some help with my new 5MW Green Laser. I bought it about 3 weeks ago and it finally arrived yesterday, I was extremely excited because my friend had his 2 arrive a week ago and they worked fantastically, but for some reason it started acting up.. It stopped working, and I tried swapping batteries, a million times. But noticed the IR 808nm was coming out instead, but oddly enough SOMETIMES the laser would work at full power, others, only IR. If I press the button really hard sometimes it gets an alright power going but not 5MW.

Does anyone know how to fix this issue, or what it could be? Thankyou.
